Abstract
A display panel is formed using a single crystal thin-film material that is transferred to substrates for display fabrication. Pixel arrays form light valves or switches that can be fabricated with control electronics in the thin-film material prior to transfer. The resulting circuit panel is then incorporated into a color display panel with a light emitting or liquid crystal material to provide the desired light valve.
